What is a Window Header?
Window headers are supports found on the upper portion of the window casing. Generally, the supports are at least twice as thick as the framing components found around the opening. The header will span horizontally across the top of the window casing, offering added support that prevents the full weight of the wall from resting on the window casing itself. Found in both residential and commercial buildings, the window header helps to add stability to the wall while making it possible to insert an opening for the window frame. A traditional window header will be located near two joists, rafters, or studs, depending on how the windows are placed. By placing this thicker and shorter wood beam under the supporting joist or rafter but over the opening for the window, there is no added stress placed on the joist. This means that after the window installation takes place, the window frame will not have to bear any load in order to keep the wall section in line with the rest of the wall. Along
